Postcolonial‟ is a multifaceted and contentious term. To define it in universally acceptable terms is quite impossible because of the doubt and suspicion allied to this relatively new field of literary studies. The attempt of this paper is to study V. S. Naipaul‟s novel Half a Life to bring forth the underlining beliefs and ideologies responsible for the birth of postcolonial nation-states. The focus is also on understanding the effects of migration and immigration on personal relations. The present research paper attempts to foreground the miserable conditions of the lives of subaltern people at their own inherited land as well as on the foreign lands and their continuous struggle and hope of assimilation in the postcolonial nationstates.V. S. Naipaul‟s Half a Life deals with the themes of cultural conflicts, migration, rumination, globalization, multiculturalism, political struggles and hope of assimilation. Further this research paper will expose the gamut of issues including the multiple exclusion and distribution faced by postcolonial nation-states, threats of migration, loss of identity, globalization, and economic disparity.
